Stealth Browser MCP server

The Stealth Browser MCP Server provides a Model Context Protocol implementation that enables stealth browser capabilities using Playwright with advanced anti-detection techniques. It allows you to navigate websites and capture screenshots while evading common bot detection systems.

Installation

To install the Stealth Browser MCP Server, you'll need to have Bun installed on your system. Then run:

# Install dependencies
bun install

Running the Server

You can start the MCP server using one of the following commands:

# Run the MCP server in production mode
bun start

# Run in development mode
bun dev

# View available tools
bun inspect

Using the Screenshot Tool

The server provides a "screenshot" tool that can capture images of webpages while using stealth browser techniques to avoid detection.

Parameters

The screenshot tool accepts the following parameters:

• url (string, required): The webpage URL to navigate to
• fullPage (boolean, optional, default: true): Whether to capture the entire page
• selector (string, optional): CSS selector to capture only a specific element
• headless (boolean, optional, default: true): Whether to run in headless mode or visible browser mode

Example Usage

When connecting to this MCP server through a compatible client, you can use the screenshot tool to capture webpages while avoiding bot detection. The server leverages multiple anti-detection techniques including:

• Modified browser fingerprints that appear as regular user traffic
• Handling of WebGL, canvas, font, plugin and other browser fingerprinting techniques

Technical Implementation

The server is built on:

• FastMCP for the MCP server implementation
• Playwright for browser automation
• playwright-extra for plugin support
• puppeteer-extra-plugin-stealth for avoiding bot detection

This combination enables robust stealth browsing capabilities that can be accessed through the Model Context Protocol.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "stealth-browser-mcp" '{"command":"bun","args":["start"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "stealth-browser-mcp": {
            "command": "bun",
            "args": [
                "start"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "stealth-browser-mcp": {
            "command": "bun",
            "args": [
                "start"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
